Specification of Letters Patent.

Patented Get. 8, 1918.

Application filed February 26, 1918. Serial No. 219,287.

To all whom it may concern:

Be it known that I, ABRAHAM BARBA- cLoUeH, a citizen of the UnitedStates of America, and resident of Gallup, in the county of McKinley andState of New Mexicm have invented certain new and useful Improvements inCar Arresting and Holding Devices of which the following is aspecification. I

This invention relates to car stopping and holding mechanism andparticularly to a device to be used at the bottom of mine shafts wherecars are stopped and held temporarily prior to their being delivered tothe hoisting cage of a mine.

An object of this invention is to provide novel means for checking themomentum and finally arresting the movement of a car, the said devicehaving novel means for preventing undue shock and vibration owing to thebraking action. p i

A further object of this invention is to provide means which might betermed a safety device to be brought into action in case the normalbrake or arresting mechanism has proven ineffective and a still furtherobject of the invention is to provide a confining gate to prevent thecar from passing into a shaft prior to the descent of the cage so as toavoid accident.

With the foregoing and other objects in view. the invention consists inthe details of construction. and in the arrangement and combination ofparts to be hereinafter more fu ly set forth and claimed.

In describing the invention in detail, reference will be had to theaccompanying drawings forming part of this specification wherein likecharacters denote corresponding parts in the several views, and in whichFigure 1 illustrates a side elevation of a device embodying myinvention;

Fig. 2 illustrates an end view thereof;

Fig. 3 illustrates a horizontal section; and

Fig. 4- illnstrates a section on the line H of Fig. 1 with the end wallin elevation.

In these drawings, I have illustrated one embodiment of the invention,although it is to be understood that with respect to certain features.the construction may be modified within certain bounds and this isespecially true with relation to the formation of the casing into whicha mine ear'is run. The casing is here shown as being rectangular and thesides as comprising double headed rails 11 with a sheathing 12 and alining 13 although as stated, this may be modified. The side linings 13preferably project at one end of the casing-and are curved as at 1 1 tocreate an enlarged opening when the cars enter. The casing has sills 15on which rails 16 are supported and guards 17 are provided to preventdisengagement of car wheels from the rails.

It is the purpose of the inventorto frictionally engage the sides of thecar to break the momentum of the car as it enters the casing and finallyto bring it to a stop within the casing prior to its being delivered toa lifting cage or ele ator. To that end; I provide a friction devicewhich may be termed a door, the same comprising outer andinner faceplates 18 and 19 respectively which incase a filler 20, preferably ofwood. The facings may be secured to the filler in any appropriate way asby rivets 21 and the inner facingplate is secured to the side lining 13by fastenings 22. The so-called gate is freeat one end to oscillate andit is held normally inward by a spring 23 whose outer end bears againsta head 24 of a rod 25. The rod operates through an aperture 26 of abracket 26 and the inner end of the rod is connected to an apertured lug27 through the medium of a pintle 28 the said apertured lug beingconnected to the door.

Within the side frame of the casing, there is an aperture 29 for thereception of a screw 30 and the screw 30 is threaded in a bolt 31 heldin the side frame so that the screw may move into and out of the casingand bear against the door to press it inwardly, the said inward pressurebeing against the ac tion of the spring 23 so that the door is preventedfrom swinging too far inwardly by the said spring. The purpose of theinventor is that the door should be in position to engage the side of acar coming into the casing and under normal conditions, the door wouldyield or spring from the point where the screw 30 engages it and therewould be suflicient rigidity of the door to insure friction which wouldcause the car to brake or come to rest, it being understood that whenthe car was moved from the casing, the spring 23 would operate toprevent the door from swinging inward beyond the point that it hadoccupied prior to the entrance of the car.

The screw 30 has a hand wheel 31' by which it can be manipulated and asecond screw 32 threaded a nut 33 near the exit end of the casing has ahand wheel-34 for formed by an extension-of the Sheathing. 12 andbending it on itself to provide'an interveningspace or eye 38 and thetapered pin is of a size to enter the eye and'bear against the link whenit is in pos'ition't'o guard the end of the casing. By reason 'of thefact that the pin is. tapered, it can be readily dislodgedfroin theeyewithout backingth car from engagement with the, link as-it will onlybe I necessary to tap the lower end of the pin slightly to effect thisdislodgmentj Asa means for guarding against accidents which might resultby reason of'a carcoming into the casingv prior to the replacement ofthe linkzor buffer; '1 have provided a hinged yoke 391which may swingfrom the" position in which it is shown in Fig'.; 2 to a position atright angles thereto at the end of" the casing so that car will strikeit if the link as stated is not inplace.

In the'present embodiment-cf the invention, the yoke is mounted 'on'thepivots 40 and L1 and it is provided-with a handle42 which may bemanipulated by forcin'gthe handle upwardly to cause the yoke to swingoutwardly across the end of the casing It will be observed fromscription and from an inspection of the drawing that a number ofmeansare pro--' vided for safeguarding the movement of" cars andthat-owlng to the presence of the screw 30, the gate maybe moved oradjusted to increase or diminish the frictional engage Copies of thispatent may be obtained for'fivecents each, by addressing the(loihinis'sioner of Patents,

in 37 which enters an eye 38 which eye 1n the present instance istheforegoing dement of the door with a car; that the spring willlimit'theinward movement of the gate which will allow outward swinging move-'inent thereo'fg' that the screw 32 may be brought into action to holdthe gate rigid under"certain conditions but which under normalconditions would be threaded out so as to normally disengage the saidgate.

The functions and purposes of the com bined' link-and buffer and of thecar need not,

it is thought, be further" described in detail.

I claim- 1. Ina ca'r' arresting-and holding device a casing, a doorhaving one end secured-tothe' casing and adapted to oscillate withrewherebya car beyond the said-point of engagementwillbe yieldingly heldand means for *yieldingly-holdirig thedoor in positionf 2.
